Start z Taiyuan 25.07. o 03:13 z Taiyuan wystrzelona została RN CZ-4B, która wyniosła na orbitę satelitę teledetekcyjnego Ziyuan-3 (3), niewielkiego satelitę telekomunikacyjnego Tianqi 10 oraz satelitę Longxia yan X shexian tance wyposażonego w teleskop rentgenowski do badania czarnych dziur.

Udany start chińskiej rakiety z satelitą obrazującym BY REDAKCJA ON 3 SIERPNIA 2020
(...) Głównym ładunkiem rakiety Długi Marsz 4B był trzeci satelita z serii jednostek obrazujących Ziyuan 3. Wyniesiony satelita posiada masę 2,5 tony i dołączył do dwóch wcześniejszych jednostek tej serii, które wyniesione zostały na orbitę w 2012 i 2016 roku. Dane zbierane przez te satelity, a de facto zdjęcia satelitarne, trafiają do chińskiego Ministerstwa Zasobów Naturalnych. Zdjęcia te są wykorzystywane w zarządzaniu rolnictwem, zasobami wodnymi, przeglądem środowiskowym czy działaniom związanym z planowaniem przestrzennym.
Dodatkowy satelita z serii Ziyuan pozwoli na uzyskiwanie danych nie co trzy dni jak wcześniej, lecz codziennie. Chiny kontynuują wykorzystywanie tej serii satelitów już od 1999 roku. Co ciekawe, w działaniach rozwojowych nad tą konstelacją pojawiła się Brazylia. Pozostałe dwie jednostki wyniesione w sobotę na orbitę zostały wyprodukowane przez firmę Shanghai ASES Spaceflight Technology Co. Ltd. Satelita Tianqi 10 został wyniesiony dla firmy Guodian Gaoke i będzie pełnił funkcje komunikacyjne. Drugi z pary mniejszych satelitów, nazwany Lobster Eye 1, będzie zaś wykonywał obserwacje astronomiczne w paśmie rentgenowskim (X).

The Ziyuan III 03 satellite is launched by a Long March-4B rocket from the Taiyuan Satellite Launch Center, July 25, 2020. China sent a new high-resolution mapping satellite into space on Saturday from the Taiyuan Satellite Launch Center in the northern province of Shanxi. The Ziyuan III 03 satellite was launched by a Long March-4B rocket at 11:13 a.m. Beijing time, according to the center. It was the 341st flight mission by the Long March rocket series. Also on board the rocket were two satellites used for dark matter detection and commercial data acquisition respectively. They were developed by the Shanghai ASES Spaceflight Technology Co. Ltd. All three satellites have entered preset orbits, sources with the Taiyuan center said.

The Long March 4B rocket lifted off from the Taiyuan Satellite Launch Center at 11:13 p.m. Eastern Friday.
The China Aerospace Science and Technology Corp., the country’s main space contractor, confirmed launch success (Chinese) within the hour.
The main payload was the Ziyuan-3 (03) remote sensing satellite, developed by the China Academy of Space Technology (CAST) under CASC. The satellite has a trio of roughly 2.5.meter-resolution cameras for producing geographic information products and resource survey and monitoring.
The new satellite will be networked with the Ziyuan-3 (01), (02) and Gaofen-7 satellites in orbit to provide stable satellite data sources. A fourth and final Ziyuan-3 series satellite may be launched this year.
Dark matter search, Apocalypse constellation
The two small sats, for x-ray astronomy and commercial data acquisition respectively, were developed by the Shanghai ASES Spaceflight Technology Co. Ltd., a research institute under the Shanghai Academy of Spaceflight Technology (SAST), a major CASC subsidiary.
The lobster eye x-ray telescope is a pioneering experiment with the involvement of Hong Kong University and Nanjing University. The stated aim of the NJU-HKU No.1 satellite is to verify ultra-large field of view imaging for searching for dark matter signals in the x-ray energy range.
Science goals include searching for hypothetical “sterile neutrino” particles the constituents of dark matter. Hot gas in galaxy clusters, solar system comets and the interaction of the solar-wind with the earth’s magnetosphere are other areas of study for the lobster eye x-ray payload.
The data acquisition satellite is understood to be part of plans by Beijing Guodian Gaoke Technology Co. Ltd. to build its ‘Apocalypse’ constellation. The satellite is part of technology verification tests for the narrow-band Internet of Things constellation. (...)
CASC stated early January that it intended to launch around 40 times in 2020. Other launch service providers such as Expace with its Kuaizhou solid rockets will be additional missions.

A Long March 4B rocket lifts off Saturday with the Ziyuan 3-03 mapping satellite and two secondary payloads. Credit: Xinhua(...) The third spacecraft in China’s Ziyuan 3 series of mapping satellites was the primary payload on the Long March 4B rocket.
The Ziyuan 3-03 spacecraft, weighing more than two-and-a-half tons, joins two other Ziyuan 3 satellites launched in 2012 and 2016 providing land survey imagery and data to the Chinese Ministry of Natural Resources. The civilian-operated satellites “provide data for the country’s land resources investigation, natural disaster prevention, agriculture development, water resource management, environmental survey and urban planning,” Xinhua said.
The addition of a third Ziyuan 3 satellite will shorten the time the Ziyuan 3 constellation can take images of the same location on Earth from once every three days to once per day, according to Xinhua.
China began launching Ziyuan satellites in 1999, and some spacecraft in the Ziyuan program have been developed in partnership with Brazil.
The two secondary payloads on Saturday’s launch were developed by Shanghai ASES Spaceflight Technology Co. Ltd., Xinhua said.
One of the satellites, named Tianqi 10, was launched for the Beijing-based company Guodian Gaoke for a communication and data relay mission. The other small secondary payload, named Lobster Eye 1, carries a wide-field X-ray astronomy instrument.
